As the title says, after a few minutes using the VestaCP panel, whether it be adding a domain, SSL certificates, emails, whatever my VPS will just crash. There doesn't seem to be any specific action I do that causes this but it seems to happen more often while adding SSL certificates. The server will still be running but everything becomes unresponsive. All of my websites, the admin panel, mail, SSH, FTP all become unresponsive. This only happens when editing things in the VestaCP panel itself. Once I manual reboot the server everything works fine until I start changing things within the control panel again. Any ideas of what could be causing this?
Edit: I'm running an AWS EC2 instance with 1 vCPU and 1gb ram and Ubuntu 16.04 and this is a fresh install on a new instance. I used to have my webserver running on the same instance but with Ubuntu 14 and Sentora CP and have never had this issue.
